1. Complete a pipetting cycle thumb short distance, meaning higher comfort

2. Compare the thumb force required by the same range of pipette to complete a fluid discharge (must press to the end), which is the key to affect the comfort, the less force means that the less the risk of finger damage caused by long-term use;

3. Loading and unloading suction head, the same is the more effort, the better;

4. The weight of the pipette is moderate, too heavy will increase the burden of the hand, but too light also often means that the material may be unsatisfactory;

5. Other ancillary designs, such as shell frosted design and finger hook design, help to further improve comfort.
